, are also properly" seouredto the axle ezising l0 at the cylindrical. part il thereof.

To reinforce zor' "further strengthenftle desi red, lloe Weld axle rinsing; nd For-the purpose of forming oil pockets 'in the tapered portions of the" axle easing, tubes 48 are secured Within the Casing, heine' preferably Welded onrrlriveted" to tloe` cylindrical ends thereof and. extendmg inwardly therefrom towardthe central tubes 4 8 are sepamted-from the .adjacent portions ofthe casing, therebyfoI-ming oil .105, portion o1" the easing. l The inner: ends of these pockets 49, which may be denominated the end oil pockets-fits'distinguished from the#r inner oil pockets that will be presently described. The inner ends of the tubes 48 are supported in the casing b supports 50, which may be in the form o having inner and outer flanges secured as by Welding to the tubes and casing. By this arrangement of the supports 50 transverse lzo vends of the tubes walls are formed adjacent the ends of the tubes 48; thereby creating oil pockets on both sides of the differential gearring, 'which oil vpockets may be denominated i ner pockets as distinguished from the end pockets hereinabove described. To make these inner pockets more effective, the inner the su ports 50 may be extended inwardly towar the differential beyond the inner .48 and 1n fact in close proximity to the lugs 33 so that very little, 1f any, o1l could be splashed into the inner ends of these extensions. These extensions 51 of the supports 50 may also support washers 52 whichsurround the axle sections and thereby prevent the oil from leaking out through the tube 48.

By reference to Fig. 2, it will be seen that the channels 16,- hereinabove referred to,-v

pass under and over the disks or supports and thereby connect the inner and end oil pockets. Bfy this construction the greater part ofthe oil in the central enlargedportion of the' axle casing is retained therein and splashed..onto the gears and',bearings,

yet considerable oil may be used withoutfear 'of its overflowing 'into the tubes 48,

even whenthe vehicle tips considerably, as

in such casethe 'outer pockets 49 will take much of the oil and return it to the enlar ed portionv of the casing whenf'the vehicle rig ts ltself.

From the above description it will be observed that the bearings for the differential 1 gearing and the driving shaft 25 areassured of constant alinementf by reason of being mounted in a single' casting, and none of these. bearingsare in any way affected by strains put upon the axle'4 casing, because they are entirely independent of `the tubes 48 which transfer many of the strains to the casing throughthe supports 50.

' AIt will 4b'frsfjperceived also that this'con- "struction requlres veryilittle machine work accurate machine wor being done u en the ABIS the axle casing, ractically all of the cover 21 and itsasociated parts. his of course facilitates manufacture considerably.

,specific embodiment of the invention has been' described in detail 'and will be 'specically claimed, but it will be u derthat t'e invention 4is not' limited to' l the exact details ofl construction shown,as it parent that'changes maybe made stood will be a without eparting from'the spirit or scope of theinvention. g y Having thus described my invention, what stamped steel disks l flanges of the inner end of the tube from t andouter-flan I claim. and desire to secure by Letters Patent is:
